How to use
Plug the Unit UT230B-EU directly into a compatible mains socket, then connect the appliance to the meter. The device will immediately display voltage and current readings and begin accumulating consumed energy while the appliance operates. For accurate short-term measurements, allow the appliance to run under typical load conditions and read the display when values have stabilized. To estimate energy cost, note the accumulated energy reading over a known period and multiply by your local electricity tariff.
Usage recommendations
Use the meter indoors on appliances within the supported voltage and current range. Avoid exposure to moisture, extreme temperatures or mechanical shock. For safety, disconnect the meter before inspecting or handling the connected appliance. Regularly check readings during typical operation to detect unusual consumption patterns and compare accumulated energy over time to assess cost impact.
